Yes, I can. Without harming the person still within.

[ An important clarification to Allen. It's something stated so simply; clean and steady. No smugness or bravado, not even technically confidence: just simple honest conviction. ]

And so can you, probably.

[ Again, conviction. The plainspoken belief in something he wants to see be fact. Even belief in someone else. ]

The process is probably different, but when it's fundamentally about cleansing the negative emotions that might be within something or someone... it's the same sort of thing, isn't it? Someone's despair or hatred, their suffering overwhelming them to that point. Even if it's caused by blood and injury, it's still that they're suffering because of something traumatic.

[ A beat, considering. ] A friend of mine, the only other exorcist I know— he talks about curses and "cursed energy" like you do. And he can exorcise it from a beast too. It isn't easy, and sometimes there isn't anything left of the person or creature they once were before to be saved, but...

...Even then, at least their soul could be put to rest.
